When I try it, it doesn't. But then I don't have any overloaded help method. So maybe that is what I need to fix.
Hmmm. Following the example here: http://www.exelisvis.com/docs/Creating_Operator_Overlo.html, I put the following in a file red::_overloadHelp.pro (the name of my class is "red"):
FUNCTION red::_overloadHelp, Varname
class = OBJ_CLASS(self)
text = 'The '+Varname+' variable is an object of class '+class
RETURN, text
END
The result:
IDL> help,scope_varfetch('self',LEVEL=-1)
<No name> OBJREF = <ObjHeapVar1(RED)>
Did not seem to take any notice of my overloaded help method.
The following also does not work:
IDL> help, self, /obj, level = -1
SELF UNDEFINED = <Undefined>
So did my overloading not work?
